Turning Long, Thin Spindles
Production turning a batch of long, thin spindles from wood with a dimension of 1¼" × 44" (32 mm × 112 cm) can be somewhat of a challenge when faced with the vibration created by the turning process. A common control method is to use a steady rest, but its use introduces a physical obstacle that requires additional time and effort to work around, limiting the production turner’s efficiency.
Myron Curtis discovered that the use of twin four-jaw chucks, each with independent jaws, stiffens the overall assembly, which significantly dampens the vibration. The addition of the turner’s hand wrapped lightly around the spindle blank makes for a very manageable turning configuration. An added benefit of using twin chucks, especially for slightly warped wood, is the ability to adjust the jaws independently to aid in the centering of the blank.
